Yes, rapid STD tests exist for several common infections, and the options have expanded significantly in recent years. Depending on the infection, you can get results in as little as 20 to 30 minutes, either at a clinic or, for some tests, entirely at home without a prescription.
Which STDs Have Rapid Tests
Rapid testing is available for more sexually transmitted infections than most people realize. HIV was the first to get widely available rapid tests, and it remains the most established option. Several rapid HIV tests deliver results from a finger prick or oral swab in about 20 minutes, with sensitivity and specificity both above 99.8% in clinical evaluations by the CDC.
Beyond HIV, rapid or point-of-care tests now cover:
- Chlamydia, gonorrhea, and trichomoniasis. In 2025, the FDA authorized the first at-home test for all three infections (the Visby Medical Women’s Sexual Health Test), which uses a vaginal swab and delivers results in about 30 minutes. It requires no prescription. In clinical trials, it correctly identified 97.2% of chlamydia-positive samples, 100% of gonorrhea-positive samples, and 97.8% of trichomoniasis-positive samples.
- Syphilis. Two rapid syphilis tests are FDA-cleared: the Syphilis Health Check and the DPP HIV-Syphilis Assay (which screens for both HIV and syphilis simultaneously). The FDA also authorized the first at-home syphilis test in 2024.
- Hepatitis C. Rapid antibody tests for hepatitis C are available at many clinics and community health settings.
There are currently no rapid point-of-care tests for herpes (HSV), hepatitis B, or HPV. These still require standard lab-based testing.
How Fast Results Come Back
The defining feature of rapid tests is that you can get an answer during a single visit or, for home tests, within the same sitting. Most rapid antibody tests for HIV and syphilis take 15 to 20 minutes. The newer molecular tests for chlamydia, gonorrhea, and trichomoniasis take about 30 minutes. Some clinic-based molecular platforms run in roughly 90 minutes, which is still fast enough for same-visit results in an urgent care or emergency department setting.
By comparison, standard lab-based STD tests typically take one to five business days for results, sometimes longer depending on the lab.
How Accurate Rapid Tests Are
Accuracy varies by infection, and this is where understanding the trade-offs matters.
Rapid HIV tests are exceptionally accurate. A CDC field evaluation of four commonly used rapid HIV tests found that all had 99.8% sensitivity (meaning they correctly caught virtually every true positive) and 99.8 to 100% specificity (meaning they almost never flagged someone as positive who wasn’t). These numbers are close enough to lab-based testing that rapid HIV tests are considered highly reliable for screening.
Rapid syphilis tests are less precise. The Syphilis Health Check, the most widely available option, has shown sensitivity ranging from about 77% to 96% and specificity from 91% to 99%, depending on the study and the population tested. That’s a wider range than most people expect, and it means rapid syphilis tests miss more infections and produce more false positives than lab-based blood draws. The DPP HIV-Syphilis Assay performs better, with syphilis sensitivity of 95 to 99% and specificity of 100% in two clinical studies.
The at-home chlamydia, gonorrhea, and trichomoniasis test performs well by rapid-test standards, with accuracy rates above 97% for all three infections. That’s comparable to many clinic-based tests.
The Window Period Still Applies
A rapid test is only as good as its timing. Every STD has a “window period,” the gap between exposure and the point when a test can reliably detect infection. Testing too early means the infection hasn’t produced enough of the markers (antibodies, antigens, or genetic material) for the test to pick up.
Here’s what the window periods look like for the most common infections:
- Chlamydia and gonorrhea: One week catches most infections. Two weeks catches nearly all.
- Trichomoniasis: One week catches most. One month catches nearly all.
- HIV (blood-based antigen/antibody test): Two weeks catches most. Six weeks catches nearly all.
- HIV (oral swab): One month catches most. Three months catches nearly all.
- Syphilis: One month catches most. Three months catches nearly all.
- Hepatitis C: Two months catches most. Six months catches nearly all.
If your most recent exposure was very recent, a negative rapid test result doesn’t rule out infection. You may need to retest after the full window period has passed.
Home Tests vs. Clinic Tests
Most home testing devices are modified versions of the same tests healthcare workers use, and their core accuracy is comparable. The difference comes down to user error. A review of 25 studies comparing self-administered HIV tests to professional-administered tests found that in about 97 to 98% of cases, untrained users achieved a valid, correct result.
The small gap comes from common mistakes: not collecting enough of the sample, spilling the buffer solution, having trouble transferring a blood drop, or misreading faint lines on the result window. Blood-based home tests tend to produce more invalid results (up to 9.5% in some studies) than oral fluid-based tests (up to 4.5%), largely because finger-prick collection is trickier for people to do on themselves.
If you use a home test, following the instructions precisely matters more than it might seem. An invalid result isn’t a negative. It means the test didn’t work and you need to test again.
When Rapid Tests Aren’t the Best Option
Rapid tests are designed for screening, and they work best for people who haven’t recently been diagnosed with the same infection. This is especially true for syphilis. Rapid syphilis tests detect a type of antibody that can remain positive for life after treatment, so if you’ve had syphilis before, a rapid test can’t distinguish between a past treated infection and a new one. Lab-based testing is the better choice in that situation.
Federal health guidelines also note that rapid syphilis tests are most useful in higher-risk populations and areas where syphilis is more common. For routine screening in low-risk individuals, lab-based tests are preferred because their higher accuracy reduces the chance of both missed infections and unnecessary false alarms.
A positive result on any rapid test should be confirmed with a follow-up lab test. This is standard practice, not a sign that rapid tests are unreliable. It simply reflects that screening tests are built to cast a wide net, and confirmation testing narrows the answer down.
Where to Get Rapid STD Testing
Rapid tests are offered at many sexual health clinics, community health centers, Planned Parenthood locations, urgent care facilities, and some emergency departments. Mobile testing vans and outreach programs in many cities also provide rapid HIV and syphilis testing, often for free.
For home testing, the Visby Medical test for chlamydia, gonorrhea, and trichomoniasis is available without a prescription. OraQuick sells an FDA-approved at-home oral swab test for HIV. At-home syphilis testing became available in 2024. These can be purchased online or at some pharmacies, though availability and pricing vary.
